" In this paper we compare the experimental findings from human electropysiological signal responses to environmental “geomagnetic” and artificial extremely low frequency (ELF) electromagnetic fields in order to determine the transfer characteristic from acupuncture meridian analysis and EEG studies. The fundamental Schumann resonance frequency is claimed to be extremely benificial to existence of the biological cycle phenomena of plants, animals and humans. However, the results from our acupuncture meridian and EEG studies have shown that frequencies between 8.8 and 13.2 Hz, which fall between peaks of the Schumann resonance, mainly correlate with analysed human electrophysiological signals, while one study proves a correlation between transfer function of Schumann resonance and electro-acupunture meridian. The results from our acupuncture meridians and EEG activity studies confirm that the human body absorbs, detects and responds to ELF environmental EMF signals. This is a classical physics phenomenon utilised in telecommunication systems, which definitelly needs to be further investigated for possible biological cell-to-cell communication phenomena."

The authors think that complex biological systems would most likely also use complex electromagnetic communication systems and that external artificial electromagnetic application randomly interferes with communication channels rather than insert new information into the communications channel.

They search for resonance characteristic of acupuncture meridian (that have less electrical resistance than surrounding media) applying a sinusoidal signal, and they found resonance in 6.72, 8.9 and 11.5 Hz.

In this point may be interesting to note that Cyril W. Smith found a 7.8 Hz resonance in the the pericardium meridian at Pe9 (a meridian that passe throught heart an in the point that terminate at the tip of the middle finger) when measured over people in meditative state but that in normal state is found to be 0.25 Hz (see this paper).

They describe various experiments results that suggest that acupuncture meridians have a selective response to frequency, these results correlate well to the low frequency peaks measured in EEG and ECG signals and this response may also have some association with the increase in alpha waves (7.5 – 13 Hz) during acupuncture stimulation. Moreover the authors think that a correlation with the resonant frequencies occurring on the natural environment may be made. Since these natural resonant frequencies due to lightning-induced electromagnetic wave propagation between the earth and ionosphere (the Schumann resonances) have been shown to overlap with the characteristic spectral components of the EEG.

" Our results could be considered to be consistent with König resonant absorption and reaction findings and confirm that the whole-body changes in conjunction with geomagnetic and Schumann resonance influence, altering brain and acupuncture meridian patterns. The results from the three studies, Ćosić et al. [13], Cohen et al. [14], Lazoura et al. [15], and Cvetković et al. [16], discussed here, definitelly reveal that the peaks of maximum skin impedance intenisty and relative differences in EEG activity are shown to occur between the two Schumann resonance outer regions which is the actual higher EEG Alpha 10Hz region. In fact, Schumann resonance acts like a ‘band-pass’ filter which allows the maximum intensity of acupuncture meridian and EEG activity to penetrate between the two Schumann resonance outer regions. Only Lazoura et al. [15] study results prove that there is a correlation between the actual Schumann resonance peaks and electro-acupunture meridians."
